420A Anyone got an oil pump or water pump

[DrewmHolland]

i'm doing a stock rebuild on my 420a and I figured I might as well replace the oil pump and water pump while i'm at it, does anyone have a good spare they'd be willing to sell me?

You'd be better off buying new or use what you got. Unless yours is bad swapping one used one for another used one is really just wasting money and there is no guarantee it will last any longer than yours would have.

That’s valid

That’s valid

How many miles are on the engine you are rebuilding? Most cases I would go with a new water pump but run the old oil pump. I would probably take the cover off and check the gerotor and plates for excessive wear as long as the engine was apart.

I know my motor has at least 215000 miles and it spun 2 bearings as well so I would feel safer just having a new oil pump, problem is most modern ones are made of junk and fall apart so I want something oem

Chrysler probably still makes those oem parts for that engine.

OEM water pump is gone. Bot the GMB 1201300 and Gates 41003 are reliable pieces, available from Rock Auto at a decent price. Melling M190 on the oil pump, also available at Rock Auto.

You can still buy the OEM water pump. Part#: 68382490AA

But with their prices varying from $65-$120 I would just buy a $15 one from RockAuto. I've never had a problem from those.
